Frequently asked questions

Is this grammar checker free to use?

Yes, completely free. The tool uses the public LanguageTool API and works without sign-up, payment, or any limits beyond the 2,000 character cap per check.

What languages are supported?

English (US), French, Spanish, German, and Arabic are available out of the box. LanguageTool supports many more languages — request more by reaching out.

How accurate is the grammar checker?

LanguageTool is one of the most respected open-source grammar engines and catches most common spelling, grammar, punctuation, and style issues. It will not catch every nuance — always re-read important text yourself.

Is there a character limit?

Yes — 2,000 characters per check. This is the limit imposed by the free public LanguageTool API. For longer texts, split them into smaller chunks.
